Expand description

The execution context which allows sending ICMP destination unreachable errors, which needs to happen when address resolution fails.

Required Methods§

Source

fn send_icmp_dest_unreachable( &mut self, bindings_ctx: &mut BC, frame: Buf<Vec<u8>>, device_id: Option<&Self::DeviceId>, original_src_ip: SocketIpAddr<I::Addr>, original_dst_ip: SocketIpAddr<I::Addr>, metadata: I::Metadata, )

Send an ICMP destination unreachable error to original_src_ip as a result of frame being unable to be sent/forwarded due to link layer address resolution failure.

original_src_ip, original_dst_ip, and header_len are all IP header fields from frame.
